whats most essential - toothbrush, shaving blade or toilet paper?

Hi All. Am a newbie here and enjoying every minute!
Don't know if you've had this discussion yet, but I really have to wonder - if someone goes on Survivor and has only one 'luxury' item to carry along - what's more essential? I guess the top options are:
a) Tooth brush
b) Toilet paper and
c) Shaving blade

What would you pick? Personally, I'm all for the shaving blade, everyone's going to stink soon anyway so a mint fresh mouth is not a polarizing factor on your appeal, plus the TV audience is none the wiser! And yeah - soft TP would be so great, but when you anyhow have to get one with nature to go, might as well make do with leaves. But the blade would be oh so useful to keep those on-display armpits in viewable condition, not to mention, keeping your bikini line in control! What think?

I put toothbrush, because I'm anal about brushing my teeth, I simply can't go to bed without brushing.... if I do, I'll pop awake sometime in the night and remember that I forgot to brush & go up and do it...

I can deal with hairy legs and leaves and grass for toilet paper, but I just hate "velvet teeth" .....

When you're ten years old and a car drives by and splashes a puddle of water all over you, it's hard to decide if you should go to school like that or try to go home and change and probably be late. So while he was trying to decide, I drove by and splashed him again. - Jack Handey
